DETAILED DESCRIPTION

Embodiments of the present disclosure will be described in detail below, and examples of the embodiments will be shown in the drawings, wherein the same or similar elements and the elements having same or similar functions are denoted by like reference numerals throughout the descriptions. The embodiments described herein with reference to the drawings are exemplary and used to generally understand the present disclosure. The embodiments shall not be construed to limit the present disclosure.

A cooking appliance 1 according to embodiments of the present disclosure will be described with reference to the drawings.

As shown in FIGS. 1 to 14 , the cooking appliance 1 according to the embodiments of the present disclosure includes a pot lid 100, a pot body 200, and a pot lid locking assembly 300.

The cross section of the pot lid 100 has a long axis and a short axis orthogonal to each other. An upper surface of the pot body 200 is provided with a limiting boss 220 (an up-down direction indicated by arrow A in FIGS. 1-6 and FIGS. 8-13 ). The limiting boss 220 abuts against an outer peripheral edge of the pot lid 100 when the pot lid 100 is closed. The pot lid locking assembly is used to lock the pot lid 100 in a closed state, and the pot lid locking assembly is disposed on at least one of the pot lid 100 or the pot body 200.

For the cooking appliance 1 according to the embodiments of the present disclosure, by making the cross section of the pot lid 100 having the long axis and the short axis orthogonal to each other, the pot lid 100 can be substantially configured to be oval. Compared with round pot lids in the related art, the cooking appliance with the oval pot lid can cook large rectangular food materials, the application range of the cooking appliance is expanded, and the operational comfort is improved.

Moreover, since the upper surface of the pot body 200 is provided with the limiting boss 220, and the limiting boss 220 abuts against the outer peripheral edge of the pot lid 100 when the pot lid 100 is closed, the limiting boss 220 can be used to limit and orient the pot lid 100 when the pot lid 100 is closed, which can not only ensure that the pot lid 100 is accurately fastened onto the pot body 200 when it is closed, but also avoid detachment of the pot lid 100 and the pot body 200 due to improper fastening. In this way, the working reliability of the cooking appliance 1 can be enhanced to improve the cooking effect of the cooking appliance 1, and the pot lid 100 can be accurately closed on the first try during operation, which avoids repeated adjustment of the pot lid 100 when the user closes the pot lid 100, thereby realizing the smooth closure of the pot lid 100, simplifying the operation process, facilitating the user's operation, and improving the operational comfort, compared with the cooking appliances in the related art.

In addition, by providing the pot lid locking assembly installed on at least one of the pot lid 100 or the pot body 200, the pot lid 100 can be locked in the closed state, so that not only the cooking effect of the cooking appliance 1 can be guaranteed during cooking, but also the reliable locking of the pot lid 100 in the closed state can be ensured, thereby enabling the cooking appliance 1 to work reliably.

Therefore, the cooking appliance 1 according to the embodiments of the present disclosure has the advantages of convenient closure of the pot lid, simple operation, and the like.

The cooking appliance 1 according to specific embodiments of the present disclosure will be described below with reference to the drawings.

In some specific embodiments of the present disclosure, as shown in FIGS. 1-13 , the cooking appliance 1 according to the embodiments of the present disclosure includes the pot lid 100, the pot body 200, and the pot lid locking assembly.

Specifically, as shown in FIG. 7 , an inner side surface 211 of the limiting boss 220 is inclined upward from the inside to the outside. In this way, when the pot lid 100 is closed, the inner side surface 211 can guide the pot lid 100 to facilitate the smooth closure of the pot lid 100.

Optionally, the height G of the limiting boss 220 from the upper surface of the pot body 200 in the vertical direction is 1-25 mm. In this way, it is convenient to realize the accurate position limiting when the pot lid 100 is fastened, so as to improve the reliability of the fastening of the pot lid 100.

Specifically, as shown in FIG. 4 and FIG. 5 , the pot body 200 is provided with two handles 212 opposite to each other in a circumferential direction of the pot body 200, and a plurality of limiting bosses 220 are provided and distributed on the two handles 212, such that the pot lid 100 can be oriented by means of the plurality of limiting bosses 220, and hence the user can close the pot lid 100 conveniently from different directions, facilitating the closure of the pot lid 100 on the first try.

More specifically, as shown in FIGS. 4 and 5 , each handle 212 is provided with two limiting bosses 220 spaced apart from each other along the circumferential direction of the pot body 200. In this way, the two limiting bosses 220 on each handle 212 can be used to position and guide the closure of the pot lid 100, so that the pot lid 100 is stressed more uniformly, avoiding the tilt of the pot lid 100 during the closure, and closing the pot lid 100 more smoothly.

Further, an upper surface of each handle 212 is provided with a limiting groove located between the two limiting bosses 220. In this way, the limiting groove can enable an axis of the pot lid 100 and an axis of the pot body 200 to be positioned automatically, which further facilitates the smooth fastening of the pot lid 100.

Optionally, as shown in FIG. 14 , the pot lid locking assembly 300 includes a guide rail 310 and snaps 320, and the guide rail 310 is provided at the pot lid 100. The two snaps 320 are oppositely arranged in the circumferential direction of the pot lid 100. The two snaps 320 can be arranged on the guide rail 310 close to each other or away from each other. When the pot lid 100 is closed, each handle 212 is located between the two snaps 320 in the circumferential direction of the pot body 200. In this way, the limiting boss 220 is arranged between the two snaps 320 in the circumferential direction of the pot body 200, and when the pot lid 100 is closed, the limiting boss 220 can limit and orient the pot lid 100 reliably, which facilitates the fastening of the pot lid 100 and improves the accuracy of the fastening of the pot lid 100, compared with the related art where snaps 320 are used for limitation and orientation but the snaps 320 cannot effectively limit the pot lid in the movement direction of the snaps 320.

Further, the guide rail is oriented along a direction of the short axis, and when the pot lid 100 is closed, the two handles 212 are disposed adjacent to both ends of the long axis respectively. In this way, it is convenient to improve the structural strength of the pot lid locking assembly and the stability of the pot lid locking assembly, and moreover, since deformation is less likely to occur in the direction of the short axis of the pot lid 100 than in a direction of the long axis, it is possible to prevent the deformation of the pot lid 100 from affecting the sliding of the snaps.

FIGS. 1 to 13 show the cooking appliance 1 according to the present disclosure. As shown in FIG. 1 , the pot body 200 includes an outer housing 230, an outer pot 240 and an inner pot 250, and the limiting boss 220 is disposed on an upper surface of the outer housing 230. The outer pot 240 is disposed in the outer housing 230. The inner pot 250 is disposed in the outer pot 240. The cooking function of the cooking appliance 1 can be realized conveniently and the working performance of the cooking appliance 1 can be improved.

Specifically, the pot lid 100 and the inner pot 250 each have an oval cross section. Due to the relatively low overall rigidity of the oval pot lid in the related art, the top of the pot lid arches up and is deformed by pressure in the pot, while the edge of the pot lid is inclined and deformed downward along a pressure-bearing step, and hence, the deformed pot lid affects the fastening effect of the pot lid. The limiting boss 220 is provided at the upper surface of the pot body 200, which can reduce the influence of the deformation of the pot lid 100 on the fastening effect of the pot lid 100, and improve the reliability and stability of the cooking appliance 1.

Optionally, a positioning boss 110 is provided at a lower surface of the pot lid 100, and a positioning groove 210 is provided at the upper surface of the pot body 200. The positioning boss 110 is fitted in the positioning groove 210 when the pot lid 100 is closed. In this way, the positioning boss 110 and the positioning groove 210 can be used to position and orient the pot lid 100 during the closure of the pot lid 100. On the one hand, the positioning boss 110 and the positioning groove 210 can realize the automatic positioning of the axes of the pot lid 100 and the pot body 200 to ensure that the pot lid 100 is accurately fastened on the pot body 200 when closed, thereby improving the working reliability of the cooking appliance 1 and upgrading the cooking effect of the cooking appliance 1. On the other hand, the user can accurately close the pot lid 100 on the first try during the operation, and avoid repeated adjustment of the pot lid 100 when the user closes the pot lid 100, thereby realizing the smooth closure of the pot lid 100, simplifying the operation process, facilitating the user's operation, and improving the operational comfort, compared with the cooking appliances in the related art.

Specifically, as shown in FIGS. 8 and 11 , the positioning boss 110 has a cross-sectional area increased gradually from bottom to top. As a result, when the pot lid 100 is fastened, the positioning boss 110 slides into the positioning groove 210 automatically through cooperation between an outer surface of the positioning boss 110 and the positioning groove 210, so that the positioning boss 110 can be used to guide the fastening of the pot lid 100 to enable the pot lid 100 to be fastened smoothly.

More specifically, the positioning groove 210 is configured as an arc groove, a V-shaped groove, or a conical groove, and the shape of the positioning boss 110 matches the shape of the positioning groove 210. As a result, the positioning boss 110 and the positioning groove 210 can be used to position and guide the closure of the pot lid 100, which can not only make the closure of the pot lid 100 smoother, but also facilitate the accurate and reliable closure of the pot lid 100.

Optionally, as shown in FIG. 10 , the pot lid 100 includes a pot lid cover plate 120 and a pot lid enclosure plate 130 connected to the pot lid cover plate 120 and extending in a circumferential direction of the pot lid cover plate 120. The positioning boss 110 is disposed on a lower edge of the pot lid enclosure plate 130. In this way, the arrangement of the positioning boss 110 can be facilitated, and the positioning boss 110 can be fitted in the positioning groove 210 conveniently.

Specifically, as shown in FIG. 10 , two positioning bosses 110 are provided and arranged oppositely in the circumferential direction of the pot lid 100. In this way, the pot body 200 and the pot lid 100 can be stressed uniformly, the stability when the pot lid 100 is closed can be enhanced, and the user can fasten the pot lid 100 from different directions.

More specifically, as shown in FIG. 10 , each positioning boss 110 is provided with a notch 111 at a lower end thereof, and two ends of each notch 111 form two fulcrums on the positioning boss 110; four fulcrums are on the same plane. Thus, the placement of the pot lid 100 can become convenient, and the pot lid 100 can be placed on a plane after being removed from the pot body 200.

Further, as shown in FIG. 11 , a distance H between two fulcrums on each positioning boss 110 is greater than 30 mm, which improves the stability of the pot lid 100 when placed on the plane.

Optionally, the pot lid locking assembly includes a guide rail, and the guide rail is disposed on the pot lid 100. Two snaps are oppositely provided in the circumferential direction of the pot lid 100, and the two snaps can be arranged on the guide rail close to each other or away from each other. When the pot lid 100 is closed, each positioning boss 110 is located between the two snaps in the circumferential direction of the pot lid 100. In this way, the limiting boss 220 is arranged between the two snaps in the circumferential direction of the pot body 200. When the pot lid 100 is closed, the limiting boss 220 can limit and orient the pot lid 100 reliably, which facilitates the fastening of the pot lid 100 and improves the accuracy of the fastening of the pot lid 100, compared with the related art where snaps are used for limitation and orientation but the snaps cannot effectively limit the pot lid in the movement direction of the snaps.

Specifically, the guide rail is oriented along the direction of the short axis, and when the pot lid 100 is closed, two positioning bosses 110 are located at two ends of the long axis respectively. In this way, it is convenient to improve the structural strength of the pot lid locking assembly and the stability of the pot lid locking assembly, and moreover, since deformation is less likely to occur in the direction of the short axis of the pot lid 100 than in the direction of the long axis thereof, it is possible to prevent the deformation of the pot lid 100 from affecting the sliding of the snaps.
